TILE-MACHINE.

I SPECIFICATION forming part of Letters-Patent No. 292,251, dated January 22., 1884.

' Application filed February .6, 1883. (No model.)

To aid whom, it may concern:

Be it known that I, J AMES W. PENFIELD, of Willoughby, in the county of Lake and State of Ohio, have invented certain new and useful Improvements in Tile-Machines; 'andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvementsin tile-machines; and it consists in certain features of construction and combinations of parts, hereinafter described, and pointed out in the claims. The object of my invention is to perfect certain devices on which I obtained Letters Patent No. 98,519, in June, 1870, andto which reference is hereinafter made in this specification.

The improvements consist of the following, t Wit: v

First. A stop and a dog, by the operation of which the cutting device is carried along with the tile while the tile is beingcut, so that the cutting-wires bear the samerelation to the tile as if the cutting were done while the tile remained at rest. I Second. The head of the machine supporting the molds is madewithabridge-tree firmly attached to it for supporting the core of the molds. The head is provided with a seat, to which differentsized molds maybe attached,

' and-the parts so arranged that the molds and their cores will come into their relative positions without adjustment, the different-sized cores being attached in turn to the saine bar or bridge-tree.

Third. To the outer end of the molds are at:

1 tached lubricators having a cavity surroundbar.

The machine to which my improvements,

7 and bricks does not seem to be very clearly made, for, the same product is sometimes called tile and sometimes called brick, and they are usually made on the same machine and of the same material. The most of my new devices are therefore equally well adapted to making either tile or brick.

.' In the drawings, Figure 1 is aside elevation of that portion of the machine usually called the cut-off table, showing some of my new devices; Fig. 2 is a cross-section taken on the line as a: of Fig. 1. Fig. 3 is a transverse sec tional view, showing my new device for holding the molds and cores. Fig. 4c shows a new device for a dog for coupling the cutting device with the endless belt. Fig. 5 shows a stop for gaging the length of tile, and also for carrying along together the tile and the cutting device while the cutting is performed. Fig. 6 is a view in perspective of my new cross- Fig.7 is a vertical cross-section taken on the line yy of Fig. 1. Figs. 8 and 9 illustrate my new device for attaching the cross-bars to the endless belt. Fig. 10 is a view in perspective of my new lubricator.

same.

. A represents the frame of a cut-off table provided with rollers journaled in the side pieces of the frame, and supporting the endless belt 13, to which are attached the cross-bars O.

D represents a frame supporting the cut-off .wires, and is attached to the rod 01, as is also the stop D and the dog D the said rod being supported in suitable bearings extending from the frame A. The frame 1), the stop D, and the dog D are preferably so attached to the rod (1 that they can each turn on the said rod, but can only move endwise, as the rod moves endwise, and therefore the frame, stop, and dog will all move endwise together. The said frame, stop, and dog have each'a pin, d, d",

and d respectively, projecting below the rod d, and that strike against the frame A when Fig. 11 is a vertical longitudinal sectional view of the ICC these respective parts are raised to desired position, and hold these parts from falling over backward. The pin (1 has also a pin extcnding laterally across the pin d" in such a manner that when the frame D is drawn forward slightly it will let the front end of the dog fall and engage the cross-bars on the endless belt, where it will remain until the said frame is again raised almost to its vertical position. The stop D should be placed the same distance from the wire that is next to it that these wires are apart on the frame D, so that when cut the piece next the stop D will be of the same length as the pieces that are between the wires.

The operation of this part of the device is as follows: \Vhen the tile first issues from the mold, the end thereof will be uneven and will require to be cut off at the point where the product first becomes perfect. For this purpose the product is allowed to pass along the table until the point where it is desired to sever it comes opposite one of the severingwires. The severing or cutting of the product is done by drawing down the frame D and pressing the cutting-wires through the product; but as soon as the said frame is drawn forward, and before the wires engage the product, the dog D is allowed to drop be tween the cross-bars, and this carries the cutting device along with product while the cutting is done. At the next cutting the product is allowed to approach the stop D, when the said stop is drawn down, so that the product butts against it. This carries along the cutting device, as before described, and the severing is accomplished. After each cutting the parts are pushed back into their first position.

Different arrangements of these devices may be had to accomplish the same end. For example, instead of the rod d moving endwise, the frame D, the stop D, and the dog D" might be coupled together by a sleeve or otherwise, and slide on the rod 01; or the said frame, stop, and dog might all be hinged to the frame, A, and this frame made to move forward on the rolls a. Heretofore each mold and its core had a bar firmly attached to them across on the inside of the machine, to hold the core in a central position inthe mold, and every time that the molds had to be changed it was necessary to dig said bar out of the clay. in which it would be firmly embedded. Also, the first cost of making so many bars was con-= siderable. My new device, as shown in Fig. 3, is intended to correct these defects.

F represents the sides of the chamber through which the clay is forced to the molds. f is the bridge-tree, supporting the core f", by means of the boltf. The said bridge-tree is firmly attached to the head G, which in turn is securely bolted to the flanges on the sides F. The head G is provided with a seat, the outside shoulder of which is at g, and the flanges of all of the different sizes of molds are made of such diameter as to nicely fit the shoulder y of the said seat. Also, the bolt f being made central with the said seat and the shoulder 9', and the cores all having been provided with a central hole to [it the said bolt, it will be seen that the molds and cores may be changed with but little trouble, and without changing or displacing any other part, and that but one bridge-tree is required for any number of molds and their respective cores.

In some cases it is desirable to have what might be called a supplemental treatment of the product after it has passed the mold. For this purpose I have invented what I call a lubricator, H, which is attached to the mold in a manner as shown in Figs. 10 and 11, the essential parts being the chamber 71, into which steam, oil, water, or any desired lubricant may be introduced, and the month h, that is made of like shape as the molds, but may be made a trifle smaller, so that it may rub on the surface of the product. The said rubbing, in combination with lubricant used as aforesaid, will give a much better finish to the surface of the product than it had when it issued from the molds.

Some of the products of the machine-such as roofing-tiles, paving-tiles, and some kinds of bricks-are greatly improved by a dressing of sand applied to their faces, sides, and edges. For this purpose I have-invented a device, a side view of which is shown in Fig. 1 and an end view in Fig. 6. This portion of it consists of a frame, a, supporting rollers that are journaled in the side pieces thereof and over which passes an endless belt, b, all supported in such a manner from the frame A, that the belt b shall press on top of the product and be carried along thereby, and made to pass around its rollers. The side pieces, a, are hinged to the frame A in such a manner that the top of them can be let down until the said side pieces, a, are in a horizontal position. The sides a are raised or lowered by the rods e, that are operated by arms c, from the roller E, that in turn is operated from the treadle a.

E represents the end of the bar of clay as it issues from the machine in shape to be cut into paving-tiles. The operation of this part of the device is as follows: The side boards, at, having first been let down, sand is scattered over them and the top of the endless belt b The boards, by means of the operators foot on the treadle c, are brought to their upright position against the web of clay E. The said web of clay being in motion, the sand from the belt I) is-rolled onto the top of the web, while the sand 011 the boards a is rubbed into the sides of the said web of clay.

If so desired, a board might be hinged to take the place of the rollers and belt b and operated and raised by the trcadle 0, so that sand could be thrown under the board on the top of the web of clay, when the board, again closing down,would rub the sand into the top of the web of clay instead of rolling it in, as with the rollers and belt.

In all cases where the productofthe machine belt.

purpose is shown in Fig. 6.

is in rectilinear formsuch as paving-tile, roofing-tile, bricks, and the like, or in a variety of other forms where one side or one portion of the product is flat-the endless belt B is used without the cross-bars, the product coming directly from the molds onto the said It 'is found. better to support a round tile not directly on the bottom .but at two points a short distance each side of the bot tom point. My improved cross-bar G for this To the high .points a at the-ends of the bar and to the central portion of the bottom b, is fastened a belt, upholstered band, web, or any such suitable device in such a manner that round tile will be supported, as aforesaid, without touching the said bottom point. This kind of crossbar, in addition to its supporting the tile in the best possible manner, has this advantage, that it will operate on several different sizes of tiles.

InFigs. 8 and 9 is shown my new device for attaching the cross-bars to the endless beltr Heretofore, if both edges of the cross-barwere fastened to the belt, the belt would not run smoothly around the rollers at the end of the frame, and beside the fastenings were liable to tear out. If, however, but one edge of the cross-bar is fastened, it is liable to be tilted edgewise and mar the tile.

My improvement consists in attaching firmly to each end of the cross-bars a strip of sheet metal, and attaching the other'end of the strips to the endless belt, the manner of which is clearly shown in the drawings. This makes so broad a surface on the belt that the bar cannot tilt. It does not interfere with the belt running smoothly around the pulleys, and also insures the cross-bar coming up with the fiat surface (and not cornerwise) against the bottom of the tile.

I have discovered that rubber belt with one side of it made of canton-flannel or some similar material with the woolly side out is an article of great value of which to make the bands,

(shown in Figs. 4 and 6,) and also of which to make the endless belt B. The rubber belt is impervious to moisture and is therefore durable and is at all times of equal flexibility,while by adding the canton-flannel or its equivalent the surface becomes more soft and yielding,

and also is so porous that a vacuum will not automatically from the treadle e for the purpose of scattering the sand as required, in- V stead of scattering the sand by the hand.

What I claim is- 1. In a tile-machine, the combination, with the cutter and an endless carrier, of a pivoted gravity dog adapted to engage the cross-bars of the endless carrier and cause the cutter to be carried along with the endless carrier, substantially as set forth.

2. In a tile-machine, the combination, with the cutter and an endless carrier, of, a pivoted gravitydog adapted to engage the cross-bars of the carrier, and devices connecting the cutter-anddog, whereby the cutter, when moved forward, will release the dog and cause it to engage theendless carrier and cause the cutter to be carried along with the endless carrier, substantially as set forth.

3. In a tile-machine, the combination,.with an endless carrier, of a stop constructed and arranged independent of the carrier and adapted to be adjusted to allow the end of the cut product to come in contact therewith and to carry the cutting device along with the carrier, substantially as set forth.

4. In a tile-machine, the combination, with the endless carriers, of an endless belt for sanding one face, and hinged side pieces for sanding the edges, substantially as set forth.

5. In a tile-machine, metal strips, by means of which the crossbars are fastened to the endless belt, substantially as shown and described.

6. The combination, with the cut-off table, of rubber belting with one surface made of canton-flannel or its equivalent with the rough side out, substantially as and for the purpose shownand described.

Intestimony whereof I sign this specification, in the-presence of two witnesses, this 25th day of January, 1888.
